roasting, broiling and sausage treating'memas for example, dri-p pans 61-61, mounted on a supporting holder 6.2 secured to rotary member 50. Thus the drip from the various articles of food will be caught 1n these pans, each pan catching the drip from one article of or one kind of food, and the pans will be rotated so, that the same-panwill .re. main under the several articles bythe rotation of-member62'by member 5() with food carrier 38. The pans'61 are preferably removable from the support-62.

A Ventilating stack 64 is ranged at one side of casing with ilues or ductsv65 and 66 the food treating chambers food treating mechanisms. f

[As explained,` the upper food treating` mechanism involving the food carrying element 3 may be thrown intooperation by itself by moving member 20 so that pin 24 willengage recess 22, whereby clutch members 16 and will become engaged and Amember 11 rotated; also that by moving member to cooking,

preferably ar- 2 and provided connecting with 'engage pin 24 withrecess 23 the lower meat to permit the operation of 'seen fromthe outside, tention to it and serving as an advertisingdey adapted to toast food articles treating mechanism involving the member 38 will be operated bythe engagement of clutch members 16 and 54. In order to operate both food treating mechanisms, member 2O4 may be moved so as to cause pin 24 to engage recess 21, whereby clutch member 16 will engage clutch member 15 `and also engage anotherv clutch member 54 and thereby cause the rotation of both members 11 and 50.

One side of the machine, which may be the back relatively to the operator tending the machine. may be providedthe machine to be thereby attracting atvice as well.

Thus it will be seen that articles of food .may be toasted or similarly-heated or treated by the upper food treating mechanism, and other articles of food may be cooked, broiled, roasted, or similarly treated by the other or lower food treating mechanism. It will also be seen that either one of these mechanisms can be' operated bv itself or that the two may be operated together.

It will be understood that changes'andl modifications may be made without from the spirit of the invention. What I claim is:
